Is a 500W PSU enough for a crossfire Radeon 4870?

[Sgt_Strider]

Is it? If not, what do you guys consider to be the bare minimum?

[Tonucci]

If its an very good quality one (able to withstand full capacity tests within specs, from credible reviewers), it should handle it no problem, along with an quad, a few HDD's etc...everything OC'ed (no sub zero extreme OC).

Reputable brand like Seasonic or Corsair, it should be ok. I would step it up to 600w or 650w if you have a quad or plan on overclocking everything.

[Sgt_Strider]

Would a Corsair HX620 be able to handle a pair of 4870s?

[Nanometer]

yes

[burebista]

Yep, but you'll need 2 PCI-E adapters.

if you're going to buy one.... save some money and get a corsair tx750.. more power, huge 60amp single rail and 4 pcie connectors. and you'll save $30 over the hx620.

I have a hx520 purhased last year, and that one is still $100 after mir...
so for $110 that tx750 is an awesome value.
